Since we are surrounded by curious developers, we know well how to bribe them best: give them devices! So we sent Marco Martin a lovely multi-touch tablet PC to write demos for us. So he sat down and came up with some cool – surprise! – multi-touch examples based on the KDE Plasma Desktop running on Windows 7.

With Qt 4.6 we introduced the new classes QGesture and QTouchEvent to control multi-touch events. You can now zoom, rotate, scroll, move objects around, click and resize objects on your (touch) screen. All right from your fingertips.

Marco uploaded some screencasts of his demos to YouTube and so did we with the ones we finalized. I have created a playlist for easy watching and inspiration. Enjoy and let us know what you think!

It’s about time. The desktop software industry have been doing minimal incremental changes for years, and definitely nothing revolutionary.

Touch, for example, exists there for ages (tablets, touch monitors), but mainstream software hold it back by making touch basically a pointer to a mouse and keyboard, mimicking the same (and poor) functionality of those very, very limited HIDs, instead of coding the freedom that touch brings to the scene.

I realize the hardware tech has evolved a lot recently, but it’s no excuse when even single touch can be made really useful, even if you need to resort to mouse/keyboard modifiers.

It’s a shame that it took a _mobile_ mentality (from a desktop company) to popularize touch/multitouch for the desktop. And only now the desktop world is waking up to (multi)touch, something I always knew it could be made much more than a gimmick it always was.

Finally, all that confirms what I’ve been seeing for some time now: that we must expect most of the new technology and ideas to come from the mobile R&D rather than from the desktop hardware, which is only pursuing raw performance, and a bit of eco friendly solutions.

Unfortunately, I’m only 23, but if I had money already I would invest where innovation is: the mobile world.
